Question regarding Ranger model 103-11

[BarclayG]

Recently purchased a 16ga Ranger at auction. Gun has full coverage engraving on receiver with inlaid ( silver) pointer on one side and setter on the other and two ducks in flight on bottom. Wood is well figured with fine line checkering in elaborate scroll. I assumed the wood, engraving, inlays and checkering were not orginal to the gun, however all the serial numbers on wood and metal match. The gun has web between the barrels and latch release on the forearm and gold plated double triggers. Any help in determining whether this gun could be factory original would be appreciated.
